I don't think that is Osatou, the eyes are different.

Reader-added tags include "I refuse", "Refusing with all your might, eh, Tani-san", and "Kokeshi".

The survey wants to be more than meets the eye, a fanboy in disguise:

Whom do you want to cosplay as?
• Tani-san
• Osatou-san
• Paper umbrella
• Kappa-san
• Penguin

I think that's less of a poll and more of a checklist.
Who wouldn't to cosplay as all of those?

If someone dressed up as my unique character, I'd totally let people take pictures of us together. I might even follow him around specifically for that purpose.
